How to wire a 2 gang intermediate switch.

Davegprince · Nov 29, 2022

Hi all, looking for a little advise on how to wire in a 2 gang intermediate switch.
I'm doing a first fix on a house extension and it's 3 storey.
I was going to put 2 way 2 gang switch down stairs, to operate ground and middle floor.
Then put 2 gang intermediate switch on middle floor and I want it to operate top floor as well as the middle floor.
Is this possible to do.
My original plan was to do 2 way switching circuits from ground floor to middle floor. Then top floor to middle floor, all with 2 gang switch so top floor and ground floor has 1 way switching.
Hopefully it makes sense to you guys.
Appreciate any help or wiring plans on the 2 gang intermediate switch.

Regards David

It is possible to do and its very simple. Is it your own house or are you doing it for someone else?

It's for someone else. Some one said about using 2 gang intermediate switch. I thought, that's not a bad idea. But when I looked at it, I wasn't sure about it. If you can help, I'd appreciate it.

Intermediate is for three way switching, you don't need it. You only need two way switching for bottom/middle middle/top.

I've got to ask, are you an electrician?

Two guesses

Surely if you are working as an electrician you should know how to wire a light switch...

You would only need an intermediate if you had a massive landing really

It sounds like you already know how to do 2 way switching.
Whichever variation you use, 2 way switching has wire linking L1 and L2 at one switch to L1 and L2 at the other switch (respectively).

A 3rd switch literally sits in the middle (and needs to be an intermediate switch that has four terminals).
